Building in Existing Contexts and Energy Refurbishment

Building in Existing Context and Energy Refurbishment

This module deals with a wide range of energy-related issues and problems in existing buildings. The lecture begins with the historical development of the construction methods of existing buildings and ends with energy concepts for the future. The correct evaluation of existing buildings is dealt with as well as the handling of pollutants and the possibilities of an energetic refurbishment in terms of construction and technical systems.

Many existing buildings are getting older. They are subject to numerous damage processes over their service life, due to the effects of weathering or mechanical stress, and need to be refurbished. This offers the opportunity to design a building in a future-oriented way. In the lecture, the energetic inventory, as well as the basics of refurbishment concepts are presented in detail and clearly conveyed with numerous examples. Deconstruction and the handling of pollutants are also dealt with.

In the case of refurbishment, both structural and technical options for energy-efficient refurbishment are discussed.

However, poorly planned refurbishments can sometimes also result in further considerably more expensive refurbishments. Here, as well, the students are taught possible sources of errors through concrete examples and how they can be avoided.

Through simulations and building balancing, a refurbishment can be worked out, evaluated and it can be found out to what extent a refurbishment is worthwhile. With regard to climate change, students are also shown developments in refurbishment.
